The hotter the amp runs, the more bias drift you can get. Couple that with a low-feedback design and you will need readjustments pretty often.
question to Plinius Amp owner
Just curious to know what is the sounding difference you experience when you switch between class A and class AB? I guess this comparison might be more objective since the rest of circuit is the same except the bias. Can you confortably draw the conclusion that class a mode is better in every aspect ?
Thanks!
Thanks!
